The results showed that the steel cord with high copper content possessed better initial adhesion property to rubber, but the adhesion property after aging decreased significantly; 结果表明,高铜镀层钢丝帘线与橡胶的初始粘合性能较好,但其老化后粘合性能下降明显;
The resilient wheelset has been widely used in light rail transit abroad, but it is in an initial phase domestically. There are very few publications on the resilient wheelset vehicle system dynamics and the nonlinear constants of the rubber that is used in wheelset. 弹性轮对车辆在国外轻轨交通上已使用较为广泛,但在国内还在起步时期,关于弹性轮对车辆系统动力学及橡胶非线性常数等的报道很少。
Designers can select the appropriate combination of initial clearance and the thickness of rubber bumper according to their target. They can also clearly see the difference of pounding effect and seismic response of bridge between this selection and other combination. 该程序自动化程度较高,设计人员根据自己的目标即可进行合适初始间隙和橡胶垫厚度组合的选择,同时还能清楚地看到选用该组合时的碰撞效应和结构响应与选用其他组合时差别的大小。
In order to enable the findings to directly instruct the design and construction, a conceptual design method and procedure of shear key is proposed to select initial clearance and the thickness of rubber bumper. And it can be realized through a high automatic program based on MATLAB. 为使研究结果能更直接地指导工程的设计和施工,提出了横向挡块减震设计的方法和步骤,用于解决初始间隙和橡胶垫厚度的选择问题,并用MATLAB进行了编程实现。
